Human papillomavirus infection and tumor microenvironment are associated with the microbiota in patients with oropharyngeal cancers—pilot study

xlomafota13 shared this article with you from Inoreader

Abstract

Background

Previous microbiome studies of oropharyngeal cancer have shown that there are differences in the oral microbiota between human papillomavirus (HPV)-positive and HPV-negative patients.

Methods

We collected saliva, normal tissue, and tumor biopsies from 13 patients with oropharyngeal cancer (eight HPV-positive, five HPV-negative). We obtained basic clinical data from each patient. Extracted DNA was 16S rRNA gene sequenced. Analysis was based on HPV status and sample site using univariate, multivariate, and mixed effect regression methods.

Results

Multivariate analysis methods separated samples based on HPV status (Adonis, p < 0.001). Comparison of patients showed that there were significant changes in microbial richness across all sites based on HPV status (linear mixed effects regression, p = 0.0002).

Conclusions

We found significant differences in overall microbial community and bacterial richness between oropharyngeal patients based on HPV status. Our results suggest that there are significant differences in the microbiome in patients with oropharyngeal cancer based on HPV status.

xlomafota13 shared this article with you from Inoreader

Bull Cancer. 2021 Jul 16:S0007-4551(21)00246-0. doi: 10.1016/j.bulcan.2021.04.019. Online ahead of print.

ABSTRACT

INTRODUCTION: Oral anticancer therapy is becoming increasingly developed; their prescription has become a common practice in oncology. However, there is a variability and diversity in prescription practice. Its magnitude has been very little studied in scientific literature. To our knowledge, this is the first study in Morocco and North Africa to evaluate the practice of prescribing oral chemotherapy.

METHODS: The authors conducted a national exhaustive cross-sectional survey, to evaluate the practice of the oral chemotherapy "Capecitabine" type prescription by Moroccan oncologists and to identify strategies to promote an adherence to oral anti-neoplasic therapy.

RESULTS: Ninety-one medical oncologists answered out of 118, from public oncology centres (29.7%), Hospital University (58.2%), and private sector (12 .1%). Thirty-four of the oncologists replied by email, 33 through phone conversation and 24 by filling paper questionnaires. In total, 32% of the cases were handwritten prescriptions, and 51.6% electronically generated. Forty-six percent of medical oncologists dedicated more time to the oral chemotherapy type Capecitabine prescription versus its intravenous equivalent 5FU. However, 33% medical oncologists take less time to this prescription, and 20.9% of them take the same time. Adherence to oral chemotherapy was evaluated by simply questioning of patients in most of the cases (94%) and 4% of medical oncologist declared that they did not evaluate this adherence. In total, 87.9% of Moroccan medical oncologists revealed that they have not received any specific training in the therapeutic education of the patient with oral anti-cancer treatment.

CONCLUSION: In Morocco, there is a great variability in prescription and follow-up practice for patients receiving oral chemotherapy. Th ere is a lack of a national standardization with regards to the procedures of prescribing and monitoring patients to ensure the quality and safety of the oral chemotherapy prescription.

xlomafota13 shared this article with you from Inoreader

J Plast Reconstr Aesthet Surg. 2021 Jun 24:S1748-6815(21)00346-6. doi: 10.1016/j.bjps.2021.06.013. Online ahead of print.

ABSTRACT

INTRODUCTION: Being obese has a significant impact on the quality of life limiting physical condition, life and professional activity, causing lack of acceptance from the environment, and a disturbing self-esteem. The main aim of this study is to identify which factors contribute to changes of self-esteem and satisfaction of female patients' body image perception as well as their correlation during the various stages of bariatric therapy.

METHODS: This prospective observational study included 438 bariatric female patients and a control group that consisted of 127 female subjects with reference body weight and BMI. Parametric data were collected in all the subgroups; anthropometric measurements and subjective assessment of body image were checked depending on the stage of bariatric treatment.

RES ULTS: The body image and self-esteem of bariatric patients is changing according to the stage of bariatric treatment. At the beginning of the bariatric pathway, patients are characterized by a negative body image and low self-esteem. Women undergoing contour lifting surgery got the highest score, even higher than women from the control group. The lowest scores are in the group entering the therapy and 24 h after surgery. A more favorable body image and a higher self-esteem were presented by patients with higher education and a better financial situation.

CONCLUSION: For female bariatric patients, the body image and self-esteem scores are higher with the consecutive stages of treatment. A more favorable body image and higher self-esteem is demonstrated with patients having a higher education and a better financial situation.

Abstract

The diverse etiopathogenesis of pulsatile tinnitus (PT) makes it a difficult condition to diagnose and treat. To describe the clinical features, investigations and diagnosis of patients presenting with pulsatile tinnitus (PT). Retrospective chart review in an otology unit of a tertiary care referral centre. All medical records of patients who had a complaint of pulsatile tinnitus during the period 1st January 2014–1st May 2020 were included in the study. Data regarding history, characteristics of tinnitus, examination findings, investigations and diagnosis were collected and analyzed. Sixty-four patients with complaints of PT presented to our clinic during this time period and were included in the study giving a prevalence of 0.09%. Definite diagnosis was made in 62 (96.8%) cases with a detailed history, clinical examination and tailored investigations. Pathologies diagnosed were paraganglioma (25%), superior semicircular canal dehiscence (20.3%), anterior infe rior cerebellar artery loop (7.8%), sigmoid sinus wall dehiscence (10.9%), sigmoid sinus diverticulum (6.25%), jugular bulb anomalies (7.8%) and hyperpneumatised petrous apex (3.1%) among others. Rare causes encountered were IgG4 disease, far advanced otosclerosis, vestibular aqueduct dehiscence and idiopathic intracranial hypertension. Pulsatile tinnitus is a rare complaint in the Otology clinic. Almost all cases of PT can be diagnosed correctly and appropriate treatment initiated with a logical approach to investigations.

ABSTRACT

We report a case of laryngeal cancer with multiple lung metastases that maintained a complete response (CR) for 18 months after discontinuing nivolumab treatment, with colitis developing 5 months after drug discontinuation. A 65-year-old man was diagnosed with T3N2cM0 stage IVA right supraglottic squamous cell carcinoma that progressed after 1 course of TPF (cispl atin, docetaxel, and 5-fluorouracil) as induction chemotherapy. He underwent total laryngectomy, bilateral neck dissection, pharyngeal reconstruction with anterolateral thigh flap, and creation of a permanent tracheostoma; extranodal extension was detected in the right cervical lymph node metastasis, and the patient underwent adjuvant radiotherapy. Multiple lung metastases occurred during radiotherapy, and the patient was deemed platinum refractory; nivolumab treatment was thus initiated. The tumor proportion score for programmed death-ligand 1-evaluated via antibody testing of the laryngeal tumor-was <1. The patient received 240 mg/body nivolumab every 2 weeks; a computed tomography performed after course 16 of nivolumab treatment confirmed a CR. He exhibited grade 2 thyroid dysfunction, grade 1 interstitial pneumonia, and grade 2 colitis after 6, 7, and 14 months of receiving nivolumab, respectively; treatment was discontinued as despite maintaining a CR, interstitial pneumonia occurred twice. Colitis appeared 5 months after nivolumab discontinuation; nevertheless, a CR was maintained after 18 months.

Ear Nose Throat J. 2021 Jul 19:1455613211031026. doi: 10.1177/01455613211031026. Online ahead of print.

ABSTRACT

Minor salivary gland cancer is a relatively uncommon disease of head and neck, arising across the upper aerodigestive tract. This is a malignant neoplasm with diverse clinical behaviors and histological types which are prognostically significant. Although complete surgical resection, with adequate free margin, is currently the treatment of choice for locoregional d iseases, the optimal treatment is still not standardized. We presented here a case of locally advanced minor salivary gland cancer that was treated by radical resection, reconstruction, and adjuvant radiation therapy at Vietnam National Cancer Hospital and had promising outcomes.

ABSTRACT

Greater superficial petrosal nerve (GSPN) schwannomas are an exceedingly rare nerve sheath tumor. The current literature search was conducted using Medline and Embase database by key search terms. Only 31 cases have been reported in the literature so far. Facial palsy, hearing loss, and xerophthalmia accounted for 48.4% (15), 41.9% (13), and 29% (9) of all cases, respectively. The middle cranial fossa approach was used in all previous reports. A retrospective review of 2 GSPN schwannomas patients treated by endoscopic endonasal approach (EEA) in our center was collected. Clinical records, including clinical features, pre- and postoperative images, surgery, and follow-up information, were reviewed. In all cases, clinical features including facial numbness and headache were found, with tinnitus in case 1, hearing loss, xerophthalmia in case 2. Imaging studies showed a solid mass that originated in the anterior of the petrous bone. Two patients were treated by EEA. Furthermore, no recurrence was found during the follow-up period (15-29 months) in both of the 2 cases after the operation. Complete resection of GSPN schwannomas can be achieved via the pure EEA. Endoscopic endonasal approach for radical removal of tumors is safe and feasible.

Ear Nose Throat J. 2021 Jul 19:1455613211033121. doi: 10.1177/01455613211033121. Online ahead of print.

ABSTRACT

OBJECTIVE: The purpose of this article is to review the literature and compile promising and clinically relevant biomarkers in autoimmune disease related to otolaryngology-head and neck surgery.

STUDY DESIGN: Narrative review.

METHODS: Pubmed and Google Scholar were queried using combined key words such as "biomarkers" and "otolaryngology." Additional queries were made with combined key words such as "biomarkers" and a particular subspecialty such as "autoimmune" or "Meniere's" to maximize yield of relevant titles. Subsequently, specific biomarkers identified, such as "anti-TPO-antibodies," were used as key words. Relevant titles were reviewed and selected for abstract review. Applicable abstracts were then selected for review of the full text.

RESULTS: Biomarkers that are currently in clinical use for the management of autoimmune diseases within the field of otolaryngology were included in this review. The compiled biomarkers were then detailed individually regarding their molecular characteristics, function, and clinical significance.

CONCLUSIONS: Based on this literature review, there are several biomarkers currently in clinical use within the field of otolaryngology relating to autoimmune diseases. The majority of these biomarkers are in the form of proteins such as Cogan peptide and c-ANCA. This survey may serve as a comprehensive resource on biomarkers for autoimmune diseases in clinical otolaryngology.

Ear Nose Throat J. 2021 Jul 19:1455613211032006. doi: 10.1177/01455613211032006. Online ahead of print.

ABSTRACT

OBJECTIVE: To confirm the relevance of upper and lower airway inflammation in eosinophilic chronic rhinosinusitis (ECRS), the effects of endoscopic sinus surgery (ESS) on lower airway functions and inflammation need to be examined in ECRS patients.

METHODS: Chronic rhinosinusitis patients with nasal polyps (25 non-ECRS, 28 ECRS) were enrolled. The 12 patient s in the ECRS group had comorbid asthma, in contrast to none in the non-ECRS group. We divided ECRS patients into 2 groups of ECRS with and without asthma. Clinical markers, including fraction of exhaled nitric oxide (FeNO), respiratory functions, and the Asthma Control Test (ACT) questionnaire, were investigated before and after ESS.

RESULTS: The FeNO levels in the ECRS with asthma group decreased after ESS. The mean FeNO levels in this group were 56.3 ppb before ESS and 24.9, 25.1, 25.0, and 15.5 ppb 1, 2, 3, and 4 months, respectively, after ESS. The mean forced expiratory rates in 1 second before and after ESS were 67.6% and 73.0%, respectively. The mean maximal expiratory flow rates at 50% of the vital capacity before and after ESS were 45.8% and 58.0%, respectively. Significant differences were observed in respiratory functions before and after ESS. The mean ACT scores in the ECRS with asthma group before and after ESS were 17.5 and 23.5, respectively. The ACT scores wer e significantly higher after than before ESS.

CONCLUSIONS: The present results indicate that ECRS and bronchial asthma are common eosinophilic airway inflammatory diseases, and ESS for eosinophilic sinusitis may improve lower airway function.
